DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 As shown, a mobile insect repellent device for field surveys includes a device main body 1; a lithium battery 2 is provided inside the device main body 1. Placing grooves 3 are provided at the upper and lower ends on the left side of the device main body 1. Heating sheets 4 are fixedly connected to the inner walls of the placing grooves 3. The heating sheets 4 are electrically connected to the lithium battery 2 through wires. A protective component is also provided on the placing grooves 3;

[0023] During operation, the lithium battery 2 supplies power to the heating sheets 4, causing the heating sheets 4 to generate heat and heat the electric mosquito repellent sheets, achieving the effect of repelling mosquitoes. This solves the problem that although existing insect repellent devices can effectively trap and kill mosquitoes, they will first attract mosquitoes to approach the device during use and cannot effectively protect field survey personnel.

[0024] Furthermore, the protective component includes a baffle 51 fixedly connected to the front and rear sides of the inner wall of the placing groove 3. A protective shell 52 is provided at the top of the baffle 51. A connection groove 53 is provided at the top of the baffle 51. A connection block 54 is inserted into the connection groove 53. The connection block 54 is fixedly connected to the front and rear sides of the bottom end of the protective shell 52. A connection cavity 55 is provided inside the connection block 54. A fixing block 56 is sleeved inside the connection cavity 55. The fixing block 56 is engaged with a fixing groove 57. The fixing groove 57 is provided on the inner wall of the connection groove 53. A spring 58 is provided on the side of the fixing block 56 away from the fixing groove 57. A release component is provided at the top of the fixing block 56; The side of the spring 58 close to the fixing block 56 is fixedly connected to the fixing block 56, and the side of the spring 58 away from the fixing block 56 is fixedly connected to the inner wall of the connection cavity 55;

[0025] During operation, when the electric mosquito-repellent sheet needs to be fixed, first place the electric mosquito-repellent sheet into the interior of the placement groove 3, and then press the protective shell 52 towards the baffle 51, so that the connecting block 54 fixedly connected to the bottom end of the protective shell 52 is inserted into the interior of the connecting groove 53. When the connecting block 54 is inserted into the interior of the connecting groove 53, the inner wall of the connecting groove 53 exerts extrusion on the inclined surface formed on the fixing block 56, causing the fixing block 56 to move towards the interior of the connecting cavity 55 under the action of the heat generated by the extrusion force, and exert extrusion on the spring 58, causing the spring 58 to undergo elastic deformation under the action of the extrusion force. When the connecting block 54 is completely inserted into the interior of the connecting groove 53, the extrusion force of the inner wall of the connecting groove 53 on the fixing block 56 disappears. At this time, the fixing block 56 returns to its original position under the restoring force of the spring 58 and is inserted into the interior of the fixing groove 57 to engage with the fixing groove 57.

[0026] Furthermore, the releasing assembly includes a connecting plate 59. The bottom end of the connecting plate 59 is fixedly connected to the top end of the fixing block 56, and the connecting plate 59 is disposed inside an activity cavity 60. The activity cavity 60 is opened at the bottom end of the protective shell 52, and the activity cavity 60 communicates with the connecting cavity 55. The connecting plate 59 is sleeved outside the screw rod 63, and a sliding assembly is provided between the connecting plate 59 and the screw rod 63. The screw rod 63 is sleeved inside the activity cavity 60, and the front end of the screw rod 63 is threadedly connected to a screw sleeve 64. The screw sleeve 64 is rotatably connected to the outer side of the protective shell 52; the sliding assembly includes sliding blocks 61. The sliding blocks 61 are fixedly connected to the upper and lower ends of the inner wall of the connecting plate 59, and the connecting plates 59 are all slidably connected inside the sliding grooves 62. There are two groups of sliding grooves 62, and the two groups of sliding grooves 62 are respectively opened at the upper and lower ends at the rear side of the screw rod 63;

[0027] During operation, when the fixing block 56 moves towards the interior of the connecting cavity 55, the connecting plate 59 fixedly connected to the fixing block 56 moves synchronously with the movement of the fixing block 56, and drives the fixedly connected sliding blocks 61 to slide inside the sliding grooves 62. When it is necessary to release the fixation of the electric mosquito-repellent sheet, first rotate the screw sleeve 64 and the anti-slip sleeve 65 to drive the screw rod 63 connected by threads to move. The screw rod 63 drives the connecting plate 59 and the fixing block 56 to move synchronously through the sliding grooves 62 and the sliding blocks 61, so that the fixing block 56 enters the interior of the connecting cavity 55 to release the engaged state with the fixing groove 57. At this time, pull the protective shell 52 in a direction away from the baffle 51, so that the connecting block 54 is disengaged from the interior of the connecting groove 53, and then the protective shell 52 can be removed, thereby replacing the electric mosquito-repellent sheet.

[0028] Furthermore, an anti-slip sleeve 65 is adhesively attached to the outer side of the screw sleeve 64. The anti-slip sleeve 65 is made of rubber material, and anti-slip lines are provided on the outer side of the anti-slip sleeve 65; a hanging rope 66 is fixedly connected to the right side of the device main body 1;

[0029] During operation, the anti-skid sleeve 65 made of rubber and the anti-skid grooves on its outer side increase the friction force, thereby preventing the screw sleeve 64 from slipping due to too little friction when rotating. The hanging rope 66 facilitates the whole device to be hung on a backpack or outside the body, thereby effectively repelling insects and protecting field investigators.

[0030] Working principle: The heating plate 4 is powered by the lithium battery 2, so that the heating plate 4 generates heat to heat the electric mosquito coil, thereby achieving the effect of repelling mosquitoes. When the electric mosquito coil is to be fixed, the electric mosquito coil is first placed inside the placement slot 3, and then the protective shell 52 is pressed against the baffle 51, so that the connecting block 54 fixedly connected to the bottom end of the protective shell 52 is inserted into the inside of the connecting slot 53. When the connecting block 54 is inserted into the inside of the connecting slot 53, the inner wall of the connecting slot 53 squeezes the inclined surface opened on the fixing block 56, so that the fixing block 56 moves toward the inside of the connecting cavity 55 under the action of the extrusion force and heat, and squeezes the spring 58, so that the spring 58 is elastically deformed under the action of the extrusion force. When the connecting block 54 is fully inserted into the inside of the connecting slot 53, the extrusion force of the inner wall of the connecting slot 53 on the fixing block 56 is small. At this time, the fixing block 56 is restored to its original position under the action of the restoring force of the spring 58 and is inserted into the inside of the fixing slot 57 and engages with the fixing slot 57.

[0031] When the fixed block 56 moves into the connecting cavity 55, the connecting plate 59 fixedly connected to the fixed block 56 moves synchronously with the movement of the fixed block 56, and drives the fixedly connected slider 61 to slide inside the slide groove 62. When the electric mosquito coil is to be released, the screw sleeve 64 and the anti-slip sleeve 65 are first rotated to drive the threaded screw 63 to move. The screw 63 drives the connecting plate 59 and the fixed block 56 to move synchronously through the slide groove 62 and the slider 61, so that the fixed block 56 enters the connecting cavity 55 to release the engagement with the fixed groove 57. At this time, the protective shell 52 is pulled away from the baffle 51, so that the connecting block 54 is disengaged from the inside of the connecting groove 53, and the protective shell 52 can be removed, thereby replacing the electric mosquito coil.

[0032] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
